How to make Deedlit's Mahlo-level notation more intuitive

(the original notation and definition can be found here)

And now to my suggestion:

Replace all instances of χ(a,b) with I(M×a+b)... And that's it!

Now we have a new collapsing function I which - as it's name implies - keeps track of our inaccessible cardinals in a very straight forward manner:

I(n) = In

I(M) = I(1,0)

I(M2) = I(1,0,0)

I(M3×5+M2×I+M×Γ₀+7) = I(5,I,Γ₀,7) = I(5,I(1),Γ₀,7)

I(Mω×5+M3×Γ₀+7) = I(1@ω, Γ₀@3, 7@0)

Of-course, once we reach I(MM), this I function stops looking like an extended Veblen function, and starts looking like a full-fledged collapsing function. So:

I(MM) = I(MI(MI(M...)))

(I think... If the last line is wrong, I'll be grateful for corrections)

(EDIT: Given that we are dealing with inaccessibles here, that last line looks wr…
